A bad circuit breaker is a major inconvenience, but there can be other issues at play when your power supply isn’t working the way it should. Breakers protect you and your home from current overloads and other electrical issues. If the circuit gets overloaded, the breaker will trip, cutting power to eliminate the risk of fire. Sometimes a breaker will trip even when there is no overload, but it can be tricky to figure out which situation applies.

If you think you have a bad circuit breaker, look out for the following signs so you can get the problem taken care of quickly.

If your breaker is tripping, it could mean there is a device on the circuit causing an overload. Identifying what circuit the breaker is protecting can help you figure out if the problem is with a device or with the breaker itself. There might be a label on the breaker panel that gives you this information, but if not, you can figure it out by testing your lights and devices. If you disconnect the devices connected to the circuit and try to reset the breaker again, the outcome will confirm whether you have a faulty breaker. If it still trips even without the devices connected to it, it is defective and needs replacement.
